Answer is: coefficient is one.
Chemical reaction: SiO₂ + 4HF → SiF₄ + 2H₂O.
Reaction is balanced when there are equal numbers of elements in both side of the chemical reaction.
HF - hydrofluoric acid, <span>highly corrosive, dissolves many materials.</span>
SiF₄ - silicon tetrafluoride.

Answer:
Answer is below with the steps in order
Explanation:
4) Blood picks up carbon dioxide from the body
7) Heart pumps carbon dioxide rich blood to the lungs
8) Inhale
9) Nose traps germs in air
10) Air moves down the trachea
3) Air moves through bronchi into the bronchioles
6) Alveoli receive oxygen pass to blood
9) Oxygen passes into the blood
11) Alveoli receives carbon dioxide from the blood
12) Oxygen-rcih blood flows to the heart
3) Carbon Dioxide moves from bonchioles to bronchi
13)Carbon dioxide flows up
1) Heart pumps oxygen-rich blood to the body
The last <em>four of five</em> steps could be switched up a little bit since it all happens synchronously, but this is the most accurate interpretation.
